be understood that the construction of each of the hangers 4- isidentical and the description of one will suiiice' for all.

The support 5 includes an outwardly cx tendingand upwardly curvedgoose-neck 7 having provided in its end a recess 8. The end of thegoose-neck T terminates short of the base 5 as will beevident from Fig.3, the obvious purpose of the intervening space being to permit theinsertion of the sheave 9 and the assemblage of the supporting elementstherefor.

The sheave f) has a semi-circular ball-race 10 which with thecoinplenlental ball-race ll of the bearing cone 12 supports a pluralityot' ball-bearings 123. The bearing cone 12 includes a sleeve H which isof such a length as to terminate evenly with the base of an annularrecess 15 in the outer surface of the sheave E).

The recess 15 receives the end of the goosetion to the support utteredby the bearings 13. Adjacent shoulders 16 and 17 respectively of thebearing cone 12 and sheave f) are rounded as indicated in Fig. 5 formingan annular groove upon which the ballbearings 13 rest and upon which theweight of the door 1 principally rests.

A lateral channel in communicating with formed by the rounded portions145 and IT. terminates at the base of the recess 1.3 where a lubricantis delivered thereto from a well 19 in the upper surface of thegoose-neck T.

A square bolt 20 is passed through the car door lptllt base 5. of thehanger l and en- A collar 21 positioned upon the bolt 20 forms a spacingmember between the head of the bolt and the rear surface of the bearingcone 12. The head of the bolt 20 being seated in a square recess at theback of the car door 1, prevents turning of the bolt and consequentlythe hearing cone 12 is held rigidly in position. It will also beobsenved that the bearing cone 12 has an additional annular flange 12which enters a similarly rear surface of the sheave 9.

Tracks 22 and23 are provided for the sup port and guidance of the door 1and sheaves 9. The tracks 22 and 23 are supported by brackets 21 at theextremities of the car 2. It will. thus be understood that nointermediate supports of any kind are provided for the tracks 22 and 23thereby ofi'ering no obstruction to the free movement of the door 1 overthe surface of the car.

Bracing strips 25 also secured to the brackets 24 and secured atintermediate points to the respective tracks 22 and 23, impartsuflicient rigidity to the tracks to prevent buckling thereof. It willbe observed that the bracing strips '25 attached to the upper tracks 22have right angularly turned flanges :25" upon which shields 26 aresecured. These shields 26 extend downwardly over the hangers 4 andeffectively cover the h angers so that foreign elements such as dust andmoisture may not collect upon the movable parts of the hanger.

An abutment strip 27 disposed in such a manner as to receive theadjacent edge of the door 1 is arranged at one side of the doorway 3 asshown in Fig. 1. A hasp 28 and staple 29 together with the lock 30 formthe securing means for the door -1. An arcuate support 31 receives thehasp when in its freed position and prevents the hasp from dangling uponits fulcrum when the door is open.

\Vhile the operation of the door is thought to be obvious, a rsumthereof is thought to boot advantage. In assembling the hanger 4. thesheave 9 is applied to the end of the goose neck 7 so that it rests inthe recess 15. The bearing cone 12 having the ball-bearings 13 is thenmoved into position when upon applying the, bolt 20 and the collar 21,the hanger may be secured upon the car door.

,The engagement of the door 1 with the side of the car will effectivelyprevent the bolt 20 from moving outwardly out of engagement with therecess 8 in the goose-neck 7.

The lubricant well 19 will feedthe lubricant continuously to the channel18 and in turn to the ball-bearings 13. The brace strips 25 prevent thesagging of the tracks 22 and 23 and an easy movement of the door isobtained requiring little physical effort to open and close the door-way3.

W'hile the construction and arrangement of the device is that of agenerally preferred form, obviously modifications and changes may bemade without departing from the spirit of the invention or the scope ofthe claims.

I claim 1. In a device of the class described, the combination of a basemember, an outwardly extending upwardly curved goose-neck having aninwardly extending upper end, said goose-neck being formed upon saidbase member and having its upper end spaced from said base member saidbase .memher having an opening l-Il alinement- With the end of saidgoose-neck, a bolt passing through the opening in said base memher andengaging the end of said goose-neck, a collar carried upon said bolt, acore carried by said bolt and being held againsbshifting in onedirection by said collar, a sheave rotatably mounted upon the end ofsaid neck and upon said core, whereby the sheave will be held againstdisplacement.

2. In a device of the class described, the combination of a base member,an outwardly extending upwardly curved goose-neck having an inwardlyextending upper end. said goose-neck being formed upon said base memberand having its upper end spaced from said base member, said base memberhaving an opening in alinement with the spaced end of said goose-neck, asquared bolt passing through the opening in said base member andengaging the end of said goose-neck. a core positioned upon said squaredbolt and fitting adjacent the end of said goose-neck, a collar carriedupon said bolt and bearing upon said core for holding the core againstshifting. a sheave rotatably mounted upon said core and the end of saidgoose-neck, a1 (1 anti-friction means interposed betwcel said core andsaid sheave.

3. In a device of the class described, the combination of a base member,a goose-neck formed upon said base member, a core having a sleevebearing upon said goose-neck, me'ans for supporting said core. saidgooseneck having a well in the top portion thereof. said sleeve having achannel communicating with said well, a sheave rotatably mounted uponsaid core and said goose-neck, whereby lubricant may be placed withinthe well to pass through said channel and lubricate the inner portionsof said sheave,

In testimony whereof I aliix my signature in presence of two witnesses.
